ovirt.te: Enable local login after pass change (autoinstall)

In autoinstall we use adminpw flag to specify the password for admin user,
and after the first login is required to change the password.
However, if user tries to login in a different shell after
changing the password it's not possible. This patch updates
ovirt.te to enable it.
